Abstract: A surface material on one or more optical components of an optical sensing system can be detected. In some embodiments, a method of detection includes generating a first image using the optical sensing system. In accordance with a determination that one or more criteria are satisfied, the one or more criteria including a criterion that is satisfied when a proportion of the first image having an intensity of light in a first intensity range is greater than a threshold, a surface material is detected on the first attachable lens.
